A method and apparatus to generate and update virtual personification using artificial intelligence comprising a system configured to perform the following. Receive data associated with a person such as text files, audio files, image files, and video files. Render a virtual personification of the person and output the virtual personification to a user, such as on a display screen. Then, receiving and interpreting a user input to generate a user request, and then updating the virtual personification. The update may include generating an audio output using the text files and the audio files of the person and/or generating a video output using the image files and the video files of the person. The audio output and the video output is presented to the user by the virtual personification and it has not previously occurred by the person or thing represented by the virtual personification.

Processor(s) of a client device can: identify a textual segment stored locally at the client device; process the textual segment, using a speech synthesis model stored locally at the client device, to generate synthesized speech audio data that includes synthesized speech of the identified textual segment; process the synthesized speech, using an on-device speech recognition model that is stored locally at the client device, to generate predicted output; and generate a gradient based on comparing the predicted output to ground truth output that corresponds to the textual segment. In some implementations, the generated gradient is used, by processor(s) of the client device, to update weights of the on-device speech recognition model. In some implementations, the generated gradient is additionally or alternatively transmitted to a remote system for use in remote updating of global weights of a global speech recognition model.

A speech synthesizer for evaluating quality of a synthesized speech using artificial intelligence includes a database configured to store a synthesized speech corresponding to text, a correct speech corresponding to the text and a speech quality evaluation model for evaluating the quality of the synthesized speech, and a processor configured to compare a first speech feature set indicating a feature of the synthesized speech and a second speech feature set indicating a feature of the correct speech, acquire a quality evaluation index set including indices used to evaluate the quality of the synthesized speech according to a result of comparison, and determine weights as model parameters of the speech quality evaluation model using the acquired quality evaluation index set and the speech quality evaluation model.
